Application characteristics of PVC foaming regulator

PVC foaming regulator will improve the production performance of PVC during the production and processing of PVC. Adding PVC foaming regulator to PVC extruded low foaming products can promote the gel of PVC, and improve the thermal strength and elongation of the melt; Improve the surface quality of products; The tiny bubbles formed by the foaming agent are stable, and the cell walls will not break and penetrate each other to form large holes. Therefore, the foam obtained is not only of low density but also of good strength. VC materials should be foamed in advance when they are used, so that PVC foaming regulators are used. When PVC foaming regulators are used to foam plastics, there are three processes. Formation of bubble core, expansion of bubble core and solidification of bubble body. For PVC foamed sheet with chemical foaming agent, the expansion of bubble core has a decisive influence on the quality of the foamed sheet.
